Q. The steps for finding a factor of the algebraic expression $7a+21b+56$ are given. Find the first error, if any.
Step 1: 7 is a common factor of each term.
Step 2: $7\left(a\right)+7\left(3b\right)+7\left(8\right)$
Step 3: $7(7a+7\times 3b+7\times 8)$

1. No error
   
2. Step 2
   
3. Step 3
   
4. Step 1
   

Q. $6a$ is a factor of the algebraic expression $36a+6\left(17a\right)$ because:

1. $6a$ is the multiple of both the terms.
   
2. $6a$ divides only the first term of the expression and is not a factor of the second term.
   
3. $6a$ is not the coefficient of both the terms.
   
4. $6a$ is the factor of both the terms and divides each term completely.
